High color intensity and easily removable mascara

ABSTRACT

Disclosed are low wax mascara compositons comprising a liquid fatty substance, an emulsifying system including a sucrose fatty acid ester and a co-emulsifier, a viscosity increasing agent, a film forming system including a film forming polymer and a co-film former, and water. Also disclosed are methods for making up and/or enhancing the appearance of eyelashes by applying said compositions to the lashes.

FIELD OF THE INVENTION

The present invention generally relates to a novel mascara composition that is low wax or wax-free, contains a sucrose fatty acid ester and is easy to remove. The invention also relates to methods of making up eye lashes with improved removability.

BACKGROUND OF THE INVENTION

Several different mascara compositions have been developed in the art using various ingredients to impart desired cosmetic properties. For example, mascaras typically contain wax which is used to provide body and volume. However, the tackiness of the wax leads to mascara compositions that clump, apply unevenly, dry the lashes, smudge, flake and are difficult to remove. Also, the tackiness of the wax limits the buildability (layering) and playtime (smoothness) of these waxes. When the wax is eliminated from the mascaras to facilitate application and removal, the compositions also lose desirably properties and tend to be runny.

The current invention provides low wax and/or wax free mascara compositions having a creamier, silkier and more hydrating or “wet” texture as compared to traditional mascaras. These compositions provide a light and soft feel to the lashes while at the same time affording good body and volume to the lashes. The compositions of the invention can be applied to lashes easily and yield smooth, homogenous layers (improved buildability and playtime) with fewer clumps than traditional mascaras. The mascaras of the invention are also easily removed with water and experience less flaking or smudging than traditional mascaras.

DETAILED DESCRIPTION OF THE INVENTION

In the following description of the invention and the claims appended hereto, it is to be understood that the terms used have their ordinary and accustomed meanings in the art, unless otherwise specified. All concentrations are by weight percent on an active basis unless otherwise indicated.

“Aqueous phase” means the phase comprising water as well as such substances of a formulation which, due to their hydrophilic character, can be mixed and/or dissolved and/or dispersed in water. The aqueous phase of the composition according to the invention is advantageously a continuous aqueous phase. A “continuous aqueous phase” means that the composition has a conductivity, measured at 25° C., of greater than 23 microSiemens/cm, the conductivity being measured, for example, using an MPC227 conductimeter from Mettler Toledo and an Inlab 730 conductivity measuring cell.

“Easy removal” means the composition may be substantially removed with a non-harsh remover, such as water, and without excessive rubbing.

“Emulsifier or emulsifying surfactant” is a term of art that is well known to those skilled in the art. See, e.g. http://pharmlabs.unc.edu/labs/emulsions/agents.htm. It is a compound that has a hydrophilic part and a lipophilic part (“amphiphilic) and facilitates the dispersion of two mutually insoluble phases, in this case the oil and water phases, assisting in the formation of the O/W emulsion. Such compounds do not have an overall electric charge in their working environment (are “non-ionic”).

“High color intensity” means dramatic visual impact of the tint, in this instance, the blackness of the lashes.

“Long playtime” means the ability to continually deposit the composition on to the lashes without the composition drying up and/or causing clumps.

“Long wear” compositions as used herein, means the compositions retain at least one property chosen from consistency, texture and color the same over extended period of time (for example 1, 2 or even as long as 8 hours) as viewed by the naked eye. Long wear properties may be evaluated by any method known in the art for evaluating such properties. For example, the consistency, texture and color of the mascara composition may be evaluated immediately following application and these characteristics may then be re-evaluated and compared after an individual has worn the mascara composition for a certain amount of time.

“Oil phase” or “oily phase” means the phase containing the lipophilic, non-ionic compounds that are liquid at room temperature (25° C.) These compounds include one or more mutually compatible non-aqueous fatty substances that are liquid at room temperature, for example organic solvents and oils (“liquid fatty substances”) as herein described, and any lipophilic additive that may be present. The oil phase does not include the charged surfactants.

“Tackiness” as used herein refers to the adhesion between two substances. For example, the more tackiness there is between two substances, the more adhesion there is between the substances. Tackiness can be measured and provided in US 2008/0095730, which, to the extent necessary, is herein incorporated by reference in its entirety.

As used herein, all ranges provided are meant to include every specific range within, and combination of subranges between, the given ranges. Thus, a range from 1-5, includes specifically 1, 2, 3, 4 and 5, as well as subranges such as and 2-5, 3-5, 2-3, 2-4, 1-4, etc.

In a preferred embodiment, the composition of the invention may be in the form of an oil-in-water emulsion (O/W). The O/W emulsions according to the invention comprise an oil phase (or lipophilic phase) dispersed in an aqueous phase. In such emulsions, the aqueous phase is thus the continuous phase of the composition while the oil phase is the dispersed phase of the composition. The oil phase is present in an amount ranging from about 3.4% to about 50%, preferably from about 5% to about 15%, most preferably about 10%, including all ranges and subranges therebetween, by weight relative to the total weight of the composition. The aqueous phase is present in an amount ranging from about 50% to about 97.6%, preferably from about 85% to about 95%, most preferably about 90%, including all ranges and subranges therebetween, by weight relative to the total weight of the composition.

The viscosity of the emulsions, measured at 25% with a Rheomat 180 viscometer at 200 rmp (revolutions per minute) using a No. 4 spindle is preferably greater than or equal to 2.4 Pa*s, preferably from 4.7 to 16.6 Pa*s, most typically 9.5 Pa*s, including all ranges and subranges therebetween. The viscosity is generally measured 10 minutes after switching on the rotation of the spindle.

The pH of the emulsion of the invention at 25° C. ranges from about 6.5 to about 8.5, most preferably about 7.3+/−b 0.3.

Cosmetic Methods

In an embodiment according to the invention, the compositions comprising an emulsifying system including at least one sucrose fatty acid ester, a co-emulsifier, a viscosity increasing agent and a film forming polymer can impart thickening and volumizing properties to the lashes, while also lengthening the eyelashes with desirable lash separation and resistance to clumping. Accordingly, another embodiment of the invention provides a method of making up/or enhancing the appearance of eyelashes by applying to the lashes topically the composition of the present invention in a sufficient amount to make up the lashes. The compositions may be applied to the eyelashes as needed, preferably once or twice daily, and then allowed to dry before subjecting to contact such as with clothing or other objects.

“Volume,” as used herein, refers to the apparent build-up of the composition on the lashes. As volume increases each eyelash is defined and stands out to the eye, creating the desirable impression of longer and fuller lashes. A composition that produces increased thickness is considered to have good volume properties. Volume may be evaluated by any method known in the art for evaluating such properties. By way of example only, volume may be evaluated by a test involving first measuring the thickness of human eyelashes or hair. The composition is then applied to the eyelashes or hair. After a period of drying, the thickness of the eyelashes or hair is once again measured. The difference in volume from before and after treatment is then determined. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available compositions.

The compositions according to various exemplary embodiments of the invention may also have improved and/or increased ease of removability, relative to similar compositions not having the at least one sucrose fatty acid ester, a co-emulsifier, a viscosity increasing agent and a film forming polymer as described herein. In various embodiments, ease of removability relates to ease of removing the composition from the lashes with warm (e.g. about 50° C. or higher) water. Optionally, conventional cleansing agents such as soap or make-up remover may also be used.

As such, the disclosure also relates to methods of improving or increasing the ease of removability of mascara compositions by incorporating into said mascara compositions at least one sucrose fatty acid ester, a co-emulsifier, a viscosity increasing agent and a film forming polymer, such as at least one latex film former, as described herein.

Another embodiment of the invention relates to a method of improving at least one property selected from long wear, comfort, playtime, buildability, color intensity, ease of removal, water and/or oil-resistance, shine, adhesion, malleability, transfer resistance and ease of removal properties by incorporating in said mascara at least one sucrose fatty acid ester, a co-emulsifier, a viscosity increasing agent and a film forming polymer as described herein.

Unless otherwise indicated, all numbers used in the specification and claims are to be understood as being modified in all instances by the term “about,” whether or not so stated. It should also be understood that the precise numerical values used in the specification, including the examples and claims, form additional embodiments of the invention, and are intended to include any ranges which can be narrowed to any to end points disclosed within the exemplary ranges and values provided. Efforts have been made to ensure the accuracy of the numerical values disclosed. However, any measured value can inherently contain certain errors resulting from the standard deviation found in its respective measuring technique.

Squalane (Sebum) Immersion Test

Each lash sample was immersed in sebum for 1 hour then rubbed 10 times (12 RPMS) on a blotter with a pendulum motion. The sample was then returned to the sebum and the process was repeated at 6 and 24 hours. The traces on the blotter were evaluated visually. The blotters were photographed and reproduced as FIG. 1 below.

The results of the test are shown in Table 3 below.

As shown in Table 3 and FIG. 1, the compositions of the invention containing a sucrose fatty acid ester (Formula X) are less likely to streak or transfer (retain same number of gray traces over time) than the comparator mascara (Formula Y), which does not include a sucrose fatty acid ester.

Water Immersion Test

Each lash sample was placed under 25° C. running water for 1 minute. The sample was then rubbed 10 times (at 12 RPMS) on a blotter with a pendulum motion. Each lash sample was then immersed in water for 1 hour, followed by rubbing 10 times on a blotter in a pendulum motion (at 12 RPMs). The lash samples were then once again immersed in water for 6 hour and 24 hour intervals and rubbed on blotter paper each time following the procedure as above. The traces on the blotter were evaluated visually.

The results of the water immersion test are shown in Table 4 below.

TABLE 4 Water Immersion Test Blotter Rubbing Results Commercial Formula Y Time mascara Formula X Point Treated lashes Treated Lashes  1 minute 8-Visible Black 3-Some Gray Traces Traces  1 hour *N/A 5-Visible Gray Traces  6 hours *N/A 4-Gray Traces 24 hours *N/A 3-Some Gray Traces *No sample remaining on the lashes as it had been washed off during the water immersion. Therefore there was little/no sample that could be transferred to blotting paper upon rubbing.

As shown in Table 4 and FIG. 2, the compositions of the invention containing a sucrose fatty acid ester are much less likely to rub off after water immersion (that is, they are more water-resistant) than the comparator mascara, which does not include a sucrose fatty acid ester.

Dry Sample/Flake Test

Samples of fake lashes coated as above-described with either Formula Y or the composition of the invention (Formula X) were allowed to dry. After drying, each sample was rubbed with a dry brush 30 times and the debris was collected on adhesive paper and evaluated visually.

The scale used for the visual evaluation of this test was as follows:

Dry Rubbing Scale for Flake Test:

Dry Rubbing Scale for FlakeTest: 0 Nothing 1 Practically Nothing 2 Few Grains 3 Some Grains 4 Grains 5 High Number of Grains 6 Very High Number of Grains

The results of this test are shown in Table 5 below.

TABLE 5 Wear of Dry Samples (FlakeTest) Comparative Formula Y mascara Treated lashes Inventive Formula X 5-High Number of Grains 2-Few Grains

As shown in Table 5 and FIG. 3, the compositions of the invention containing a sucrose fatty acid ester are less prone to flake off the lashes than the comparator mascara, which does not include a sucrose fatty acid ester.

Ease of Removal Test:

1.5 mL of makeup remover was applied on a piece of cotton pad (common method of removal). Each sample was held tightly between the pieces of cotton folds for 10 seconds, then withdrawn gently. The soaked cotton was changed and the process was repeated with fresh cotton pads each time until all makeup was removed from the sample (if possible). Results are expressed in number of cotton pads used for the majority of makeup removal in relation to the total number of cotton pads used to remove the makeup. The results are shown in Table 6 below.

TABLE 6 Ease of RemovalTest Results # of Cotton Pads # of Cotton Pads for Majority of Sample for Full Removal Removal Comparator 13 10 Commercial Mascara- Formula Y Mascara of Invention- 9 7 Formula X

As shown in Table 6 above and FIG. 4 below, the composition of the invention containing a sucrose fatty acid ester (FIG. 4B) was more easily removed from test lashes with the makeup remover (it takes fewer pads to remove the mascara) than the commercially-available comparator mascara (FIG. 4A), which does not include a sucrose fatty acid ester.

Homogeneous, Uniform Coverage Test:

Mascara was applied onto each set of fake lashes as follows:

-   -   The mascara wand was dipped into the test mascara composition         once and twisted; excess product was removed from the tip of the         wand.     -   The blink simulator was run for eight (8) rotations with each         lash set.     -   The mascara wand was dipped into the mascara composition once         again and twisted; excess product was removed from the tip of         the brush.     -   The blink simulator was run for seven (7) rotations for each         lash set.     -   Each lash set was allowed to air-dry in the laboratory for         thirty (30) minutes.

6 lash sets were prepared and evaluated for each formula. Images were taken of each lash set.

The results of this test are shown below in FIGS. 5A and 5B. As shown in these figures, in the lashes treated with the mascara Formula X (FIG. 5B), the mascara film is deposited more evenly (smoother and more consistent) than in the lashes treated with the commercially-available mascara Formula Y (FIG. 5A).

Tests for Buildability, Playtime and Fewer Clumps:

In this test, a mascara composition of the invention (Formula X) was compared with two commercially available mascara compositions: Formula Y and Covergirl Clump Crusher® mascara. The mascara was applied onto each lash set following the same procedure as described above for the Homogeneous/Uniform Coverage Test. Six (6) lash sets were prepared and evaluated for each of the three mascara compositions tested. Images were taken of each lash set. The number of clumps was evaluated by visual inspection. The results of this test are shown in Table 7 below.

TABLE 7 Average Clumps After Application Mascara Formula X Mascara Formula Y Clump Crusher 6 12 9.8

As is shown if Table 7 above and FIG. 6 below, lashes treated with the mascara of the invention, Formula X (FIG. 6A), are smoother and have fewer clumps than those treated with either of the commercially available comparator mascaras; Formula Y (FIG. 6B) or Covergirl Clump Crusher mascara (FIG. 6C).

Test for Color Intensity: Wet Masstone LAB Evaluation

Two sets of lashes were independently treated with either the inventive mascara Formula X or commercially-available comparator mascara Formula Y. The color intensity of the lashes was then measured using a colorimetric spectrophotometer.

The colorimetric spectrophotometer measures the entire visible spectrum of light (rainbow) being reflected from a sample and then using mathematical tables representing the human eye color sensitivity and mathematical tables representing the color output of different light sources, calculates the result.

Color Scales:

The color scales used for this test are the Hunter L,a,b and the CIE L*,a*,b* scales. These are 3-dimensional scales. Both are based on the opponent-colors theory that states that the red, green and blue human eye cone responses are re-mixed into black-white, red-green, and yellow-blue, opponent coders as they move up the optic nerve to the brain.

The L,a,b type of scales simulate this as:

-   -   L (lightness) axis—0 is black, 100 is white     -   a (red-green) axis—positive values are red; negative values are         green and 0 is neutral     -   b (yellow-blue) axis—positive values are yellow; negative values         are blue and 0 is neutral

All colors that can visually be perceived can be measured in L,a,b scale. This test specifically refers to the L values as it is the measure of black versus white. As 0 is black, the lower the L value, the darker the color. The results of this test are provided below in Table 8.
